Description

  The present invention relates to an information processing apparatus, a program, and a communication system.

  2. Description of the Related Art Distribution systems that distribute content data such as video from a live relay camera installed at a distribution source to a plurality of terminals via a communication network such as the Internet are known. As an example, there is an example in which video and audio of a nursery school and a kindergarten are distributed to a guardian's terminal by a distributor. As a result, the guardian can confirm the state of the child in the park, which is advantageous in strengthening the security in the park and eliminating the anxiety of the guardian.

  However, when a password or the like for a guardian to browse content data leaks to the outside, anyone can view the video in the park. For such inconvenience, it is effective that only terminals that are permitted to view the video in the park can view the content data. Hereinafter, such a terminal or a person having a terminal will be referred to as “having an account”.

  Also, not only the guardian has an account, but also the grandparents can browse the content data if the child's grandparents have an account, for example. However, it may be difficult for grandparents or the like to operate the terminal themselves to obtain an account. Although it is possible for the nursery school to issue an account to the grandparents, it is also a burden for the nursery school to distribute the account to all the grandparents of many parents.

  Therefore, for example, using the fact that accounts are distributed to parents at the time of admission, etc., it is considered that parents issue guest accounts for relatives in association with parents' accounts (for example, (See Patent Document 1). Patent Document 1 discloses a server that generates new account information when an account issuance request is received from a logged-in user terminal, and records it in the account data table in association with the account information of the logged-in user. . Such a method eliminates the need for grandparents to operate the terminal to acquire an account or to distribute the account by the nursery school.

  Therefore, in the case of a nursery school, a guardian can issue a guest account to a grandparent or the like with the authority of the guardian instead of the nursery school. Those having the authority to issue such an account will be referred to as masters. On the other hand, since the guest account issued by the master is issued with the authority of the master, when the guest views the video, the master preferably performs some kind of approval.

  However, there is a problem that the burden on the master is heavy if the guest always needs to be approved by the master when viewing the video.

  In view of the above problems, an object of the present invention is to provide an information processing apparatus that can reduce the burden on the user of the other terminal when receiving video on one terminal.

  The present invention is an information processing apparatus that performs processing for a terminal to receive a video distributed by a distribution source, and acquires a distribution request for the video and account information of the second terminal from a second terminal Based on the request acquisition means, the account information of the first terminal read from the account information storage unit in which the account information of the second terminal and the account information of the first terminal are associated, the first terminal A determination means for determining whether or not the terminal is receiving video distribution, and in response to a determination result by the determination means, the first terminal notifies the first terminal that there has been a video distribution request. Notification means for notifying the user.

  It is possible to provide an information processing apparatus that can reduce the burden on the user of the other terminal when receiving video on one terminal.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

FIG. 1 is an example of a diagram schematically illustrating video distribution by the transmission system of the present embodiment. First, FIG. 1A will be described.
(1) A communication ID (hereinafter referred to as a guardian ID) of a guardian of a kindergarten and a communication ID (hereinafter referred to as a grandparent ID) such as a grandparent issued by the guardian are registered in association with each other. The communication ID is an account for logging in to the transmission management system 50.
(2) A guardian logs in to a transmission management system 50 described later.
(3) Next, the grandparent logs in to the transmission management system 50 using the grandparent ID.
(4) The transmission management system 50 determines whether or not a guardian with a guardian ID associated with the grandparent ID is logged in the transmission management system 50.
(5) Since the guardian is logged in in FIG. 1A, the transmission management system 50 notifies the guardian's terminal having the guardian ID of a message notifying that the guest has logged in.
(6) In addition, the transmission management system 50 starts distributing video to the terminal of the grandparent ID.

  Therefore, when a guardian having a guardian ID is logged in, the guardian can know that the grandparent has logged in by receiving the notification. Since parents have confirmed whether or not videos that are preferred for viewing by non-parents have been distributed, they can check the viewing status of grandparents simply by notifying parents, and parents always check grandparents. It is unnecessary to approve.

Next, FIG. 1B will be described.
(1) The grandparent ID is associated with the guardian ID and registered.
(2) In FIG. 1B, the guardian is not logged in to the transmission management system 50.
(3) Next, the grandparent or the like logs in to the transmission management system 50 using the grandparent ID.
(4) The transmission management system 50 determines whether or not a guardian with a guardian ID associated with the grandparent ID is logged in the transmission management system 50.
(5) Since the guardian is not logged in in FIG. 1B, the transmission management system 50 sends an approval request for inquiring whether to approve or reject the grandparent's browsing to the guardian's terminal having the guardian ID. To do.
(6) The guardian confirms the approval request, approves or rejects the grandparent's login, and transmits it to the transmission management system 50.
(7) If the guardian approves, the transmission management system 50 starts distributing the video to the terminal of the grandparent ID.
(7 ') When the guardian does not approve (when it refuses), the transmission management system 50 transmits a message indicating that it has not been approved.

  Therefore, when the guardian having the guardian ID is not logged in, the grandparents cannot view the video unless the guardian approves it. That is, since the guardian cannot confirm whether or not a video that is preferably viewed by a person other than the guardian is distributed, the viewing can be prohibited until the guardian approves it.

  Thus, in the transmission system of this embodiment, the guardian can grasp the login state of the grandparents who log in as a guest. Depending on the login status of the guardian, it is possible to automatically select whether the approval is required or only the notification, and it is possible to appropriately set the guardian's procedure necessary for the grandparents to view the video.

<Terminology>

<Functional parts of terminal>
Next, each part of the terminal will be described in detail. The transmission / reception unit 11 is realized by the network I / F 111 illustrated in FIG. 3, and transmits / receives various data to / from other terminals, devices, or systems via the communication network 2. The transmission / reception unit 11 starts receiving state information indicating the state of each terminal as a destination candidate from the management system 50 before starting a call with a desired destination terminal. This status information includes not only the operating status of each terminal 10 (the status of ON line or OFF line) but also the detailed status such as whether a call is in progress or waiting even if it is an ON line. Indicates. In addition, the status information is not limited to the operating status of each terminal 10, but the cable is disconnected from the terminal 10 at the terminal 10, audio is output but no image is output, or audio is not output ( Various states such as MUTE) are shown. Below, the case where status information shows an operation state is demonstrated as an example.

  An example of various data that the transmission / reception unit 11 transmits / receives to / from other terminals, devices, or systems via the communication network 2 will be described. For example, the transmission / reception unit 11 transmits start request information to the management system 50 when the user specifies a destination terminal and starts communication. The start request information includes start request information by normal transmission and start request information by entry transmission (distribution).

  The start request information by normal transmission is information transmitted when requesting the start of communication in which any terminal 10 can participate (hereinafter referred to as “communication for call”). The normal transmission start request information includes a communication ID for identifying a request source terminal, a communication ID for identifying a destination terminal, and information “Invite” indicating that a call start is requested by communication for a call. .

  The start request information by entering the room is information transmitted when requesting the start of a conference to be performed by communication (hereinafter referred to as “distribution communication”) in which one or more terminals 10 specified in advance can participate. The start request information by entering the room includes a communication ID for identifying the request source terminal, a communication ID for identifying the destination terminal, and information “Invite + Room” indicating that the start of the call by the communication for distribution is requested. . A conference to be performed by communication for distribution is identified by a conference room ID. In addition, the communication for delivery may be identified from the start request information by entering the room by including the conference room ID instead of the communication ID in the start request information by entering the room. Thereby, a later-described conference management unit 59 of the management system 50 retrieves a communication ID of a later-described entrance management DB 5007 using the communication ID of the destination terminal as a search key, and acquires a conference room ID of the retrieved record. Thus, the process of specifying the conference room used for communication can be omitted.

  After transmitting the start request information to the management system 50, the transmission / reception unit 11 receives a session ID and relay device connection information for identifying communication from the management system 50. The relay device connection information is information (such as the IP address and port number of the relay device 30 and authentication information required for connection of the relay device 30) necessary for connecting to the relay device 30 used for communication.

  In addition, the transmission / reception unit 11 receives start response information from the management system 50. The start response information is information indicating whether or not communication with the destination terminal is possible. The start response information includes a communication ID of the destination terminal, information indicating permission (Accept) or rejection (Reject) of the start of the communication, and a session ID for identifying the communication. When the start response information received from the management system 50 indicates that communication with the destination terminal is possible, the transmission / reception unit 11 transmits the communication session ID and relay device connection information to the relay device 30.

  In addition, the transmission / reception unit 11 transmits a room entry request to the management system 50 when the user selects a meeting room (conference room name) from a meeting room list image (see FIG. 8C) described later and starts communication. To do. The room entry request includes the communication ID of the request source terminal, information “Invite + Room” indicating that the start of a call by communication for distribution is requested, and the conference room ID of the conference room.

  The operation input receiving unit 12 is realized by the operation button 108 and the power switch 109 shown in FIG. 3 and receives various inputs by the user. For example, when the user turns on the power switch 109 shown in FIG. 3, the operation input accepting unit 12 shown in FIG. 5 accepts the power on and turns on the power. Further, when receiving an operation input for selecting a destination terminal from a screen on which a list of destination terminals is displayed, the operation input receiving unit 12 receives start request information by entering a room or starting request information by making a normal call. To the transmission / reception unit 11. In addition, the operation input receiving unit 12 transmits and receives a room entry request to the management system 50 when an operation input for selecting a conference room from a conference room list image (see FIG. 8C) described later is received. 11 is requested.

  The login request unit 13 is realized by a command from the CPU 101 shown in FIG. 3, and the authentication (login) is performed from the transmission / reception unit 11 to the management system 50 via the communication network 2 when receiving the power ON. The login request information indicating that the request is made and the current IP address of the terminal 10 as the request source are automatically transmitted. The login request information includes a communication ID for identifying the terminal 10 that is the own terminal as a request source, and a password for logging in to the transmission system 1. When the user turns the power switch 109 from the ON state to the OFF state, the transmission / reception unit 11 transmits the state information indicating that the power supply is turned off to the management system 50, and then the operation input reception unit 12 completely turns the power supply. Turn off. As a result, the management system 50 side can grasp that the terminal 10 has been turned off from being turned on.

  The imaging unit 14a is realized by an instruction from the CPU 101 shown in FIG. 3 and the camera 112a and the imaging device I / F 113 shown in FIG. Output image data. The voice input unit 15a is realized by the voice input / output I / F 116 shown in FIG. 3, and after the user's voice is converted into a voice signal by the microphone 114a, voice data related to the voice signal is input. The audio output unit 16a is realized by the instruction from the CPU 101 shown in FIG. 3 and the audio input / output I / F 116 shown in FIG. 3, and outputs an audio signal related to the audio data to the speaker 115a. The sound is output from 115a.

After the user's voice is converted into a voice signal by the external microphone 114b, the voice input unit 15b inputs voice data related to the voice signal. The audio output unit 16b is realized by a command from the CPU 101 shown in FIG. 3, and outputs an audio signal related to the audio data to the external speaker 115b and outputs audio from the external speaker 115b.

  The display control unit 17 is realized by a command from the CPU 101 illustrated in FIG. 3 and performs control for displaying image data on the external display 120. For example, the display control unit 17 performs control to display on the display 120 a screen displaying a list of destination terminals, a conference room list image (see FIG. 8C), which will be described later, and the like.

  Further, the storage / reading processing unit 18 is executed by the instruction from the CPU 101 shown in FIG. 3 and the SSD 105 shown in FIG. 3 as an example, and stores various data in the nonvolatile storage unit 1000 or a nonvolatile storage. Processing for reading various data stored in the unit 1000 is performed. The nonvolatile storage unit 1000 stores a communication ID (Identification) for identifying the terminal 10, a password, and the like. Further, the storage / reading processing unit 18 stores various data in the volatile storage unit 1100 and reads out various data stored in the volatile storage unit 1100. The volatile storage unit 1100 overwrites and stores image data and audio data received when a call is made with the destination terminal. Among these, the image is displayed on the display 120 by the image data before being overwritten, and the sound is output from the speaker 115a by the sound data before being overwritten.

  The session control unit 19 is a call session (an example of a “first session”) for making a call with another terminal 10 and a distribution session for transmitting audio data to the other terminals 10. (An example of “second session”) is connected.

  The session control unit 19 stops the transmission of audio data in the distribution session when connecting the call session while the distribution session is connected. For example, the state of the session and the type of the session are stored, and when it is detected that the call session is connected while the distribution session is connected, or the voice from the management system 50 When the distribution stop request is received, the distribution microphone is muted or the audio data is excluded from the distribution session. Thereby, it is possible to prevent howling and to prevent the content of a private call from being leaked to the user of the terminal 10 receiving the distribution.

  When the session control unit 19 cannot connect a call session or receives a recording request from the terminal 10 that is the destination of the call session, the session control unit 19 records content data such as video and audio, and stores the recorded content data. Then, the data is transmitted to the destination terminal 10 of the call session via the management system 50.

  The session control unit 19 is connected to a distribution session and receives a call session connection request while receiving content distribution, and responds based on a response operation from the user or the management. When the system 50 requests withdrawal (exit) from the distribution session, the system 50 leaves the distribution session.

  Note that the communication ID of this embodiment and a relay device ID described later are identification information for uniquely identifying the terminal 10 and the relay device 30, respectively. The identification information is a language, characters, symbols, various signs, or the like. The communication ID and the relay device ID may be identification information in which at least two of the language, characters, symbols, and various indicia are combined. The same applies to the session ID and conference room ID.

  The destination list creating unit 20 creates a destination list (destination terminal status list information) based on information of “multiple session permission flag”, destination list information, status information, and conference room presence information described later.

  In the destination list, the destination list creation unit 20 displays information indicating that a call cannot be made to the terminal 10 that is in an active state where incoming calls cannot be made. For example, the destination list creation unit 20 creates a list so that a button to be transmitted to the terminal 10 whose operation state is “ON line (during a call)” or “OFF line” cannot be pressed. On the other hand, a list is created so that a button to be transmitted to the terminal 10 whose operation states are “ON line (call possible)” and “ON line (during transmission)” can be pressed.

  When the terminal 10 cannot connect a plurality of sessions in parallel and the terminal 10 is connected to a distribution session or a call session, the destination list creation unit 20 Information indicating that transmission to each terminal 10 is not possible is displayed. Specifically, when the information of the “multiple session permission flag” notified from the management system 50 is not on, it is determined that the terminal 10 cannot connect a plurality of sessions in parallel.

  The destination list creating unit 20 uses the display control unit 17 to display the created destination list on the screen.

(Each functional part of the management system)
Next, each functional unit of the management system 50 will be described in detail. In the following, in describing each part of the management system 50, a relationship with main constituent elements for realizing each part of the management system 50 among the constituent elements shown in FIG. 4 will also be described. The management system 50 includes a transmission / reception unit 51, a terminal authentication unit 52, a state management unit 53, a terminal extraction unit 54, a terminal state acquisition unit 55, a relay device selection unit 56, a session management unit 57, a session control unit 58, and a conference management unit 59. A storage / reading processing unit 60, a determination unit 61, and a notification unit 62. Each of these units is a function or means realized by any one of the constituent elements shown in FIG. 4 operating according to a command from the CPU 201 according to a program stored in the ROM 202.

  The transmission / reception unit 51 is executed by the network I / F 209 illustrated in FIG. 4, and transmits / receives various data to / from other terminals, devices, or systems via the communication network 2.

  For example, when the user of the terminal 10 specifies the destination terminal and starts communication from the screen on which the destination terminal is displayed in a list, the transmission / reception unit 51 sends the start request information by entering the room or the start request information by normal transmission to the terminal 10 Receive from.

  Further, after receiving the start request information from the terminal 10, the transmission / reception unit 51 transmits a session ID and relay device connection information for identifying communication to the terminal 10.

  Further, after receiving the start request information from the communication request source terminal 10, the transmission / reception unit 51 sends the start request information, the relay device connection information, and the IP address of the management system 50 to the communication destination terminal 10. Send.

  In addition, after receiving the start response information from the communication destination terminal 10, the transmission / reception unit 51 transmits the start response information to the communication request source terminal 10.

  The terminal authentication unit 52 searches the terminal authentication management table in the nonvolatile storage unit 5000 using the communication ID and password included in the login request information received via the transmission / reception unit 51 as a search key, and the terminal authentication management table Terminal authentication is performed by determining whether the same communication ID and password are managed.

  In order to manage the operating state of the request source terminal that has requested login, the status management unit 53 stores the communication ID of the request source terminal, the terminal name of the request source terminal, the operating status of the request source terminal, the management system. 50 stores and manages the reception date and time when the login request information is received and the IP address of the request source terminal in association with each other.

  Among these, the state management unit 53 sets (changes) the state information of the terminal 10 in the terminal management table when the information indicating that the state of the terminal 10 has been changed is received from the terminal 10. For example, when the user of the terminal 10 turns the power switch 109 of the terminal 10 from the OFF state to the ON state, the terminal 10 transmits status information indicating that the power source is turned ON to the management system 50. When the state management unit 53 receives the state information via the transmission / reception unit 51, the state management unit 53 changes the operating state of the terminal 10 in the terminal management table from “OFF line” to “ON line (call possible)”. Further, when the user turns off the power switch 109 of the terminal 10 from the ON state, the terminal 10 transmits status information indicating that the power is turned off to the management system 50. When the state management unit 53 receives the state information via the transmission / reception unit 51, the state management unit 53 changes the operating state of the terminal 10 in the terminal management table from “ON line (call possible)” to “OFF line”.

  When the state management unit 53 receives information indicating that the state of the terminal 10 has been changed from the terminal 10, the state management unit 53 notifies each of the other terminals 10 destined for the terminal 10 of the changed operation state. Thereby, the display of the operating state of the terminal 10 whose state has been changed is updated on the screen in which the destination terminals displayed on the other terminals 10 are displayed as a list.

  Specifically, the state management unit 53 searches the communication ID of the destination terminal in the destination list management table using the communication ID of the terminal 10 whose state has been changed as a search key, and sets the terminal 10 whose state has been changed as the destination. Each other terminal 10 to be extracted is extracted. Then, the operation status of the terminal 10 whose state has been changed is notified to each of the other extracted terminals 10.

  The terminal extraction unit 54 searches for the communication ID of the request source terminal in the destination list management table using the communication ID of the request source terminal that requested the login as a search key, and extracts the communication ID of the destination terminal of the searched record. The terminal extraction unit 54 extracts the terminal 10 identified by the extracted communication ID of the destination terminal as a destination terminal candidate that can talk to the request source terminal.

  For each destination terminal candidate communication ID extracted by the terminal extraction unit 54, the terminal state acquisition unit 55 searches for the communication ID in the terminal management table using the communication ID as a search key, and the operation status of the searched record Is read. Thereby, the terminal state acquisition unit 55 can acquire the operating state of the candidate destination terminal that can make a call with the request source terminal that has requested the login.

  The relay device selection unit 56 generates a session ID for identifying a session in which call data is communicated between terminals. The relay device selection unit 56 searches the relay device selection management table based on the communication ID of the request source terminal and the communication ID of the destination terminal included in the start request information sent from the request source terminal. The corresponding relay device ID is extracted. The relay device selection unit 56 selects the relay device ID of the relay device 30 whose operation state is “ON line” from among the relay devices 30 managed in the relay device management table. Make a selection.

  The session management unit 57 manages a distribution session for transmitting content data from one terminal to one or more other terminals and a call session for transmitting content data bidirectionally between a plurality of terminals. To do. Specifically, the session management unit 57 associates the session ID generated by the session ID generation unit 56a, the communication ID of the request source terminal, and the communication ID of the destination terminal with the session management table of the nonvolatile storage unit 5000. Remember and manage. In addition, the session management unit 57 stores and manages the relay device ID of the selected relay device 30 for each session ID in the session management table. In addition, the session management unit 57 stores the session ID of the communication for distribution identified by the conference room ID in association with the conference room ID in the conference room management table.

  The session control unit 58 performs session management processing. In this session management process, the session control unit 58 receives a connection request (outgoing) from the terminal 10 or a connection request (incoming call) from the terminal 10 while the terminal 10 is connected (established). ), It is determined whether to permit the connection request based on information managed by the terminal management DB 5003. If the session control unit 58 determines to permit, the session control unit 58 transfers the connection request to the destination terminal 10. If not permitted, the connection request is rejected and an error is returned to the requesting terminal 10. A detailed example of the session management process will be described later.

  When the session control unit 58 receives a response to the connection request from the destination terminal 10 or receives a connection request to the destination terminal 10, the session control unit 58 determines the destination based on the information managed by the terminal management DB 5003. Terminal 10 determines whether a plurality of sessions can be connected in parallel. If the destination terminal 10 cannot connect a plurality of sessions in parallel, or if the destination terminal 10 is connected to another session, the session control unit 58 moves the destination terminal 10 from the other session. Let go. In this case, if the destination terminal 10 is connected to another session, the session control unit 58 causes the destination terminal 10 to leave the other session and then to the destination terminal 10. The connection request may be transferred. As a result, the destination terminal 10 does not need to have a function of responding to another session while one session is connected, so that a normal terminal 10 that cannot handle multiple sessions at the same time can be used as the destination terminal 10. It becomes.

  When the terminal 10 serving as the distribution source connects (establishes) a call session to the terminal 10 while the distribution session is connected to the terminal 10 serving as the distribution source, the session control unit 58 It is determined whether audio data from is transmitted. When the voice data is transmitted, for example, the relay apparatus 30 instructs the terminal 10 to stop the transmission of the voice data or discards the voice data transmitted from the terminal 10 in the distribution session. To stop transmission of audio data. In that case, the session control unit 58 sends to each terminal 10 connected to the distribution session, for example, “Voice distribution is currently stopped because the distribution source is busy”. Notify by voice or message that transmission of voice data has stopped.

  The conference management unit 59 stores and manages the conference room ID and the communication ID in the room entrance management table of the nonvolatile storage unit 5000 in association with each other. In addition, the conference management unit 59 stores and manages the conference room ID, the conference room name, and the session ID in the conference room management table of the nonvolatile storage unit 5000 in association with each other.

  The conference management unit 59 receives an entry request indicating the start of communication for distribution identified by the conference room ID from the communication request source terminal 10 via the transmission / reception unit 51. The room entry request includes the communication ID of the request source terminal and information (conference room ID or communication ID of the destination terminal) for specifying the conference room to be entered. The conference management unit 59 identifies the conference room ID of the conference room to be entered from the information for identifying the conference room included in the entry request, and the communication ID of the requesting terminal 10 included in the entry request is the conference room It is determined whether it is associated with the ID. When the conference management unit 59 is associated, the conference management unit 59 requests the session management unit 57 to perform the session management processing for the communication for distribution related to the room entry request.

  The storage / reading processing unit 60 (corresponding to the destination terminal information management unit) stores various data in the nonvolatile storage unit 5000 or the volatile storage unit 5100, or is stored in the nonvolatile storage unit 5000 or the volatile storage unit 5100. To read various data.

  When there is a room entry request from the guest terminal 10, the determination unit 61 determines whether or not the guest master is viewing the video (in other words, whether the guest is in the conference room). Further, the determination unit 61 determines whether or not the current date is included in the valid period in which the guest communication ID is valid.

  The notification unit 62 notifies the master terminal 10 that the guest is about to view the video in a manner corresponding to the determination result of the determination unit 61. That is, when the determination unit 61 determines that the master is not browsing the video, an approval request for inquiring whether to approve or reject the guest browsing is transmitted to the master terminal 10 and the determination unit 61 determines that the master is browsing. If it is determined, the fact that the guest enters the conference room is transmitted to the master terminal 10. In addition, the notification unit 62 makes various notifications to the terminal 10.

<Guest entry management table>
The registration method to the guest room entry management table will be described with reference to FIG. FIG. 6A shows an example of a screen 511 displayed on the terminal 10 operated by the master when a guest is registered in the guest entry management table. The screen 511 in FIG. 6A is displayed when the master operates the terminal, logs in to the management system 50 with the master communication ID, and moves to the registration site.

  In the master communication ID column 512, the master inputs the master communication ID. Alternatively, the communication ID of the master is automatically displayed upon login. The communication ID of the master is the communication ID distributed from the nursery school (basically, the one owned by the child's parents). In the effective period column 513, the master sets a period during which the guest can view the nursery school video. As shown in FIG. 6B, since the selectable period is displayed by pull-down or the like, the master can set the valid period simply by selecting. The master can choose only the days that he wants to see a particular event, or he can choose all the events of the year. Also, any day can be set.

  In the relationship column 514, the master inputs the relationship between the master and the guest. This is mainly to allow the nursery school side to check who the guest is. If the guest has already obtained a communication ID (for example, a guest) in the communication ID column 515, the master inputs the communication ID. Thereby, the person who acquired communication ID can browse an image | video as a guest.

  The new communication ID acquisition button 516 is a button for the terminal to request the management system to issue a guest communication ID. It is necessary to input at least the master communication ID column, the validity period column, and the relationship column. The validity period addition button 518 is a button for the master to add the validity period of the already issued guest communication ID. It is necessary to input at least the communication ID column 512 of the master, the validity period column 513, and the communication ID column 515 you have. The master communication ID link button 517 is a button for connecting a communication ID already possessed to the master communication ID. Any communication ID can be registered as a guest communication ID. It is necessary to input the master communication ID column 512, the validity period column 513, the relationship column 514, and the communication ID column 515 you have. The extension application button 519 is a button for the master to extend the validity period of the guest communication ID for one year. This is because the guest communication ID is deleted at the end of the year in which the communication ID was created.

<< Processing or Operation of Embodiment >>
First, with reference to FIG. 7, the outline | summary of operation | movement of the transmission system 1 in the case of performing a telephone call during delivery in embodiment is demonstrated. FIG. 7 is a sequence diagram of the transmission system 1 when a user makes a call during distribution. In the example of FIG. 7, at least one of video and audio is distributed from the terminal 10aa (nursery school) to the terminals 10ab (guardian's terminal), 10ba (guardian's terminal),. In this example, a call is made from the terminal 10aa to the terminal 10ab. In the example of FIG. 7, the management system 50 and the relay device 30 are described as one unit for the sake of simplicity, but transmission of content data such as video and audio is performed via the relay device 30.

  The distribution source terminal 10aa requests the management system 50 to start a distribution session by designating a predetermined conference room ID (step S101).

  The management system 50 starts a distribution session (step S102). A method for establishing a session for distribution is known. For example, each terminal is authenticated by the communication ID and password, and the management system 50 registers the operating state in the terminal management table. Since the terminals associated with each other in the destination list management table can start a session, when the other terminal requests connection of the session to the management system 50, the session between the terminals is established. As a result, one record is registered in the session management table.

  The distribution source terminal 10aa enters the distribution conference room and transmits the distribution video and audio (step S103).

  The plurality of delivery destination terminals 10ab, 10ba,... Specify a predetermined conference room ID, connect to the delivery session of the management system 50 (steps S104-1, S104-2), and connect the relay device 30. Then, the video and audio for distribution from the terminal 10aa as the distribution source are received (steps S105-1 and S105-2).

  In response to the call connection operation specifying the destination from the user, the terminal 10aa transmits a connection request (start request information) to the terminal 10ab of the specified destination to the management system 50 (step S106). Note that, before the call connection operation, an operation for requesting a destination list from the user may be accepted, and a destination may be designated from the destination list acquired from the management system 50.

  The management system 50 performs session management processing (step S107), and transfers the connection request to the destination terminal 10ab (step S108).

  When receiving the connection request, the destination terminal 10ab performs incoming processing (step S109), and returns a response to the management system 50 in response to a response operation from the user (step S110).

  The management system 50 performs terminal management and session management (step S111). Specifically, the value of “number of sessions” associated with the requesting terminal 10aa in the terminal management DB 5003 is increased by one. The “operation state” associated with the destination terminal 10ab in the terminal management DB 5003 is changed to “ON line (during a call)”. Further, the session management DB 5005 records the session ID, the ID of the requesting terminal 10aa, the ID of the destination terminal 10ab, and the like.

  If the “operation state” associated with the destination terminal 10ab in the terminal management DB 5003 is “ON line (during transmission)”, the management system 50 disconnects the destination terminal 10ab from the distribution session. A request is made (step S112).

  The destination terminal 10ab terminates the distribution session, and notifies the management system 50 of disconnection from the distribution session (step S113).

  The management system 50 removes the destination terminal 10ab from the distribution session (step S114).

  When the audio data is transmitted from the request source terminal 10aa in the distribution session, the management system 50 instructs the request source terminal 10aa to stop transmitting the audio data in the distribution session (step S115).

  The requesting terminal 10aa stops the transmission of audio data in the distribution session (step S116).

  The management system 50 notifies the distribution destination terminal 10ba connected to the distribution session that the distribution of the audio data has been stopped (step S117).

  The management system 50 transfers the response from the destination terminal 10ab to the requesting terminal 10aa (step S118).

  The requesting terminal 10aa connects the call (step S119), and starts communication between the two parties with the terminal 10ab (step S120).

  The requesting terminal 10aa transmits a disconnection request addressed to the terminal 10ab to the management system 50 in response to a call disconnecting operation from the user (step S121).

  The management system 50 performs terminal management and session management (step S122). Specifically, the value of “number of sessions” associated with the requesting terminal 10aa in the terminal management DB 5003 is decreased by one. The “operation state” associated with the destination terminal 10ab in the terminal management DB 5003 is changed to “ON line (call possible)”. Further, the session ID, the ID of the terminal 10aa, the ID of the terminal 10ab, etc. recorded in the session management DB 5005 are deleted. The management system 50 transfers the disconnection request to the destination terminal 10ab (step S123).

  The destination terminal 10ab ends the communication between the two parties with the terminal 10aa (step S124).

  Next, an example of the screen display of the distribution source terminal 10aa of FIG. 7 will be described with reference to FIG. FIG. 8A is an example of a display screen when the terminal 10aa activates the distribution function. The terminal 10aa displays a “video distribution” button 501 and a “participant edit” button 502. FIG. 8B is a screen display example when the “video distribution” button 501 is pressed in FIG. 8A and the video is distributed in step S103 of FIG. The video of the camera 112a being distributed is displayed on the display 120 of the terminal 10aa that is the own device. Also, the terminal 10aa displays a “contact” button 503. When the “contact” button 503 in FIG. 8B is pressed, a destination list is displayed, and the nursery school user can select the destination of the call as described in FIG.

  FIG. 8C shows an example of a screen display displayed by the delivery destination terminal 10ab of FIG. FIG. 8C is an example of a display screen when the terminal 10ab activates the distribution application. Information indicating conference rooms for delivery (AA nursery school and BA nursery school) where the terminal 10ab of the video delivery destination can enter is displayed. The AA nursery school and the BA nursery school have a room entry button 1301, and the guardian can enter the conference room by pressing the room entry button 1301. The entry button 1301 in FIG. 8C may be used as a button for displaying the details of the conference room. In this case, the guardian can enter the conference room from the entry button 1301 on the conference room detail screen in FIG. .

  FIG. 8D shows a screen display example when entering a conference room for video distribution. The content data distributed from the distribution source terminal 10aa is displayed.

<< New conference room creation >>
A detailed example of the distribution function using the conference room (distribution room) of the transmission system 1 in step S101 to step S105 in FIG. 7 will be described. The distribution function is a function for performing communication for distribution in which participation between the request source terminal and one or more destination terminals is restricted. First, a process for creating a new conference room for distribution will be described.

  When the operation input receiving unit 12 of the terminal 10 receives an operation input indicating pressing of a new creation button of the conference room from the user, the display control unit 17 of the terminal 10 displays a newly created conference room image on the terminal 10. FIG. 9 is a diagram showing a new conference room creation image displayed when creating a new conference room.

  Here, the flow of processing of the terminal 10 and the management system 50 when the user newly creates a conference room will be described by taking the case of the user of the terminal 10aa as an example. FIG. 10 is a sequence diagram illustrating a process when a new conference room is created.

  The operation input receiving unit 12 of the terminal 10aa receives an operation input indicating that the new creation button has been pressed from the user (step S501). The transmission / reception unit 11 of the terminal 10aa transmits a destination terminal information acquisition request including the communication ID “01aa” of the terminal 10aa to the management system 50 (step S502).

  The terminal extraction unit 54 of the management system 50 receives the destination terminal information acquisition request via the transmission / reception unit 51. Based on the communication ID “01aa” of the terminal 10aa included in the destination terminal information acquisition request, the terminal extraction unit 54 obtains destination terminal information (communication ID, terminal name, and operating state) of the destination terminal associated with the terminal 10aa. Obtain (step S503). Specifically, the terminal extraction unit 54 first searches for the communication ID of the request source terminal in the destination list management DB 5004 using the communication ID “01aa” of the terminal 10aa included in the destination terminal information acquisition request as a search key. The communication ID (“01ab”, “01ba”, “01bb”,...) Of the destination terminal of the retrieved record is acquired. Next, the terminal extraction unit 54 searches the communication ID of the terminal management DB 5003 using each of the communication IDs of the destination terminal (“01ab”, “01ba”, “01bb”,...) As search keys, Get the terminal name and operating status of the retrieved record. For example, when the search key is “01ba”, the terminal extraction unit 54 acquires the terminal name “BA terminal” and the operation state “ON line (call possible)” from the record of the terminal management DB 5003.

  Next, the terminal extraction unit 54 transmits destination terminal information including the communication ID, the terminal name, and the operating state acquired in step S503 via the transmission / reception unit 51 to the terminal 10aa (step S504). The display control unit 17 of the terminal 10aa receives the destination terminal information via the transmission / reception unit 11. The display control unit 17 displays a newly created conference room image (see FIG. 9) including the communication ID of the destination terminal information, the terminal name, and the operating state on the terminal 10aa. The operation input reception unit 12 of the terminal 10aa receives an operation input indicating the name of the conference room and the selection of the terminal 10 that can participate in the conference (step S505). The operation input reception unit 12 of the terminal 10aa transmits the conference room new creation information including the conference room name and the communication ID of the terminal 10 that can participate in the conference to the management system 50 via the transmission / reception unit 11 (step S506).

  Next, the conference management unit 59 of the management system 50 receives the conference room new creation information via the transmission / reception unit 51. The conference management unit 59 newly creates a conference room ID corresponding to the conference room name included in the new conference room creation information. The conference management unit 59 creates a record that associates the conference room ID with the conference room name in the conference room management DB 5008. In addition, the conference management unit 59 creates a record that associates the conference room ID with the communication ID included in the new conference room creation information in the room entrance management DB 5007 (step S507).

  The conference management unit 59 transmits a conference room information registration notification indicating that a new conference room has been created via the transmission / reception unit 51 to the terminal 10aa (step S508). Upon receiving the conference room information registration notification via the transmission / reception unit 11, the display control unit 17 of the terminal 10aa displays a registration completion image including information indicating that the conference room registration is completed on the terminal 10aa (step S509). .

<< Entering the conference room >>
FIG. 11 is a sequence diagram showing processing when the terminal 10 enters the distribution conference room in step S104 of FIG. Here, a case where the master terminal 10ab enters the room will be described.

  The operation input receiving unit 12 of the terminal 10ab receives an operation input for starting the distribution application (step S541). Next, the transmission / reception unit 11 of the terminal 10ab transmits a conference room list acquisition request including the communication ID “01ab” of the terminal 10ab to the management system 50 (step S542).

  Next, the conference management unit 59 of the management system 50 receives the conference room list acquisition request via the transmission / reception unit 51. The conference management unit 59 acquires the conference room ID and conference room name of the conference room related to the communication ID “01ab” of the terminal 10ab based on the communication ID “01ab” of the terminal 10ab included in the conference room list acquisition request. (Step S543). Specifically, the conference management unit 59 first searches for a record in the entrance management DB 5007 using the communication ID “01ab” of the terminal 10ab included in the conference room list acquisition request as a search key, and conferences of the searched records Acquire the room ID (1 and 2). Next, the conference management unit 59 refers to the conference room management DB 5008 and acquires the conference room names (AA nursery school and BA nursery school) of the conference room ID (1 and 2).

  Next, the conference management unit 59 transmits the conference room list information including the conference room ID and the conference room name acquired in step S543 via the transmission / reception unit 51 to the terminal 10ab (step S544). The display control unit 17 of the terminal 10ab receives the conference room list information via the transmission / reception unit 11. The display control unit 17 of the terminal 10ab displays a conference room list image including the conference room name of the conference room list information on the terminal 10ab (step S545). Thereby, the display screen of FIG. 8C is displayed. The master can enter the room from the screen of FIG. 8C, or may enter from the room entry button 1301 of FIG.

  Next, the operation input reception unit 12 of the terminal 10aa receives an operation input indicating selection of an AA nursery school included in the conference room list image from the user (step S546). The transmission / reception unit 11 of the terminal 10aa transmits a destination terminal information acquisition request including the conference room ID “1” of the AA nursery school to the management system 50 (step S547).

  The conference management unit 59 of the management system 50 receives the destination terminal information acquisition request via the transmission / reception unit 51. Based on the conference room ID “1” of the AA nursery included in the destination terminal information acquisition request, the conference management unit 59 communicates with the communication ID (“01ab”, “01ba” of the destination terminal associated with the conference room ID “1”. And “01bb”).

  Next, the terminal extraction unit 54 searches the communication ID of the terminal management DB 5003 using each of the communication IDs of the destination terminal (“01ab”, “01ba”, and “01ca”) as search keys, and finds the searched record Get the terminal name and operating status. For example, when the search key is “01ab”, the terminal extraction unit 54 acquires the terminal name “AB terminal” and the operation state “OFF line” from the record of the terminal management DB 5003 (step S548).

  Next, the terminal extraction unit 54 transmits destination terminal information including the communication ID, the terminal name, and the operating state acquired in step S548 via the transmission / reception unit 51 to the terminal 10aa (step S549).

  The display control unit 17 of the terminal 10aa receives the destination terminal information via the transmission / reception unit 11. The display control unit 17 displays a conference room detail screen (see FIG. 13) including the communication ID of the destination terminal information, the terminal name, and the operating state on the terminal 10aa (step S550).

  The operation input accepting unit 12 of the terminal 10 (request source terminal) accepts a conference room selection operation input (step S551).

  Next, the transmission / reception unit 11 of the terminal 10 receives the communication ID of the request source terminal that pressed the room entry button 1301, the information “Invite + Room” indicating that the start of the call by the communication for distribution, and the conference of the conference room. A room entry request including the room ID is transmitted to the management system 50 (step S552). The room entry request is a request for video viewing and a video distribution request.

  The conference management unit 59 of the management system 50 receives the room entry request via the transmission / reception unit 51. The conference management unit 59 determines whether a record that matches the combination of the conference room ID and the communication ID included in the room entry request exists in the room entry management DB 5007 (step S553). In step S553, it is determined whether a record that matches the combination of the conference room ID and the communication ID included in the room entry request is registered in the room entry management DB 5007, whether a session is established, or the like.

  The conference management unit 59 performs processing according to the determination result of step S553 (step S554). If the room can be entered, the session ID and the relay device connection information (IP address, authentication information, port number, etc. of the relay device 30) are transmitted to the request source terminal that transmitted the room entry request.

  FIG. 12 is a flowchart showing processing according to the result of the room entry determination. When there is no record that matches the combination of the conference room ID and the communication ID included in the room entry request in the room entry management DB 5007 and the result of the room entry determination by the meeting management unit 59 of the management system 50 is not room entry OK (step S554-1). , No), the transmission / reception unit 51 transmits error information indicating that the room cannot be entered to the request source terminal that has transmitted the room entry request (step S554-7).

  When a record that matches the combination of the conference room ID and the communication ID included in the room entry request exists in the room entry management DB 5007 and the result of the room entry determination by the conference management unit 59 of the management system 50 is room entry OK (step S554). 1, Yes), the process proceeds to step S554-2.

  The session management unit 57 determines whether communication using the conference room specified by the conference room ID included in the room entry request has already been performed (whether the session has already been established) (step S554-). 2). Specifically, the session management unit 57 searches the conference room management DB 5008 using the conference room ID included in the room entry request as a search key, and whether the session ID is set in the session ID field of the searched record. Determine whether or not. That is, the session management unit 57 determines that a session has already been established when a session ID is set in the session ID field of the retrieved record.

  If a session has already been established (step S554-2, Yes), the session management DB 5005 is searched using the session ID as a search key, and the request included in the room entry request is included in the destination terminal field of the searched record. The communication ID of the original terminal is added, and the operation state associated with the communication ID included in the room entry request is set to “ON line (during transmission)” in the terminal management DB 5003 (step S554-3), and step S554-6. Proceed to

  The session management unit 57 creates a new session ID and creates a new record in the session management DB 5005 (step S554-4).

  Next, the conference management unit 59 searches the conference room management DB 5008 using the conference room ID included in the room entry request as a search key, and newly creates it in the session ID field of the searched record in step S554-4. A session ID is set (step S554-5).

  Next, the transmission / reception unit 51 transmits the session ID and the relay device connection information (IP address, authentication information, port number, etc. of the relay device 30) to the request source terminal that transmitted the room entry request (step S554-6). . With the above processing, the processing for connecting the request source terminal to the relay device is completed. Next, the request source terminal transmits relay request information to the management system 50, and starts processing for requesting call data relay. Thereby, the request source terminal that has transmitted the room entry request by accepting the selection of the meeting room name included in the meeting room list from the user starts communication for distribution using the meeting room.

<< Display of entry button based on guest's communication ID >>
Next, processing when a guest enters the conference room will be described.

FIG. 14 is an example of a sequence diagram illustrating a procedure for displaying an entrance button 1301 for a guest to enter the conference room.
S1: The guest inputs the communication ID (abab) notified from the master and activates the distribution application.
S2: As a result, the transmission / reception unit 11 of the guest terminal 10abab transmits the guest communication ID (abab) to the management system 50.
S3: The conference management unit 59 of the management system 50 searches for conference rooms that can be entered. That is, the entrance management table and the guest entrance management table are searched to determine whether or not the guest communication ID is included. By this determination, it is determined whether the communication ID is that of the guest or the master. In the following, different cases will be described depending on whether it is a master or a guest.

When the communication ID is registered in the entry management table (when it is the master communication ID)
S4: The conference management unit 59 of the management system 50 notifies the terminal 10abab of a conference room that can be entered. This process is the same as steps S543 and S544 in FIG.
S5: The transmission / reception unit 11 of the terminal 10abab receives the conference room that can be entered, and the display control unit 17 displays the conference room that can be entered (see FIG. 8C).

When a communication ID is registered in the guest entry management table (when it is a guest communication ID)
S6: The conference management unit 59 of the management system 50 reads the validity period associated with the guest communication ID from the guest room entry management table. Based on whether or not the current date is included in the validity period, the conference management unit 59 determines whether or not video viewing is possible.
S7: If the current date is not included in the validity period, the conference management unit 59 of the management system 50 notifies the guest terminal 10aba that there is no conference room that can be entered.
S8: The transmission / reception unit 11 of the terminal 10abab receives information that there is no conference room that can be entered, and the display control unit displays that there is no conference room that can be entered.

S9: When the current date is included in the validity period, the conference management unit 59 of the management system 50 notifies the guest terminal 10abab of a conference room that can be entered. This process is the same as steps S543 and S544 in FIG.
S10: The transmission / reception unit 11 of the guest terminal 10abab receives the conference room that can be entered, and the display control unit displays the conference room that can be entered (see FIG. 8C).

  FIG. 15 is an example of a flowchart showing processing performed by the management system 50 in the processing of FIG. The process in FIG. 15 starts when the guest activates the distribution application (S1).

  The conference management unit 59 of the management system 50 searches the room entry management table and the guest room entry management table (S3).

  By the search, the conference management unit 59 determines whether the communication ID is a guest or a master (S3-2).

  If it is determined in step S3-2 that the communication ID is the master communication ID, the conference management unit 59 of the management system 50 notifies the terminal 10abab of a conference room that can be entered (S4).

  If it is determined in step S3-2 that the communication ID is the guest communication ID, the determination unit 61 of the management system 50 reads the valid period associated with the guest communication ID from the guest room entry management table (S6).

  Then, based on whether or not the current date is included in the valid period, the determination unit 61 determines whether or not video viewing is possible (S6-2).

  When browsing is not possible (No in S6-2), the notification unit 62 of the management system 50 notifies that there is no conference room that can be entered in the guest terminal 10abab (S7).

  When browsing is possible (Yes in S6-2), the notification unit 62 of the management system 50 notifies the guest terminal 10abab of a conference room that can be entered (S9).

  In this way, when a guest is requested to enter with the guest's communication ID, the guest can enter the conference room only during the valid period.

<< Room entry processing >>
Next, the processing of the transmission system 1 after the guest presses the entry button 1301 will be described with reference to FIGS. FIG. 16 is an example of a sequence diagram illustrating a procedure for a guest to enter a conference room.

  S1: The operation input receiving unit 12 of the guest terminal 10aba receives an operation input indicating that the room entry button 1301 is pressed.

  S2: The transmission / reception unit 11 of the guest terminal 10abab includes the communication ID of the request source terminal that has pressed the room entry button 1301, the information “Invite + Room” indicating that a call start is requested, and the conference room ID of the conference room An entry request is transmitted to the management system 50.

  S3: The conference management unit 59 of the management system 50 receives the room entry request via the transmission / reception unit 51. The conference management unit 59 determines whether a record that matches the combination of the conference room ID and the communication ID included in the room entry request exists in the guest room management DB 5009.

  S4: When the record that matches the combination of the conference room ID and the communication ID included in the room entry request is not in the guest room management table of the guest room management DB 5009, the conference management unit 59 of the management system 50 sets the guest terminal not to enter the room. Notice. In this case, the process in FIG. 16 ends.

  S5: A case where a record that matches the combination of the conference room ID and the communication ID included in the room entry request is in the guest room management table of the guest room management DB 5009, and the conference management unit 59 of the management system 50 determines that the room is OK. explain. In this case, the session management unit 57 determines whether communication using the conference room specified by the conference room ID included in the room entry request has already been performed (whether the session has already been established). Specifically, the session management unit 57 searches the conference room management DB 5008 using the conference room ID included in the room entry request as a search key, and whether the session ID is set in the session ID field of the searched record. Determine whether or not. That is, the session management unit 57 determines that the session has already been established when the session ID is set in the session ID field of the retrieved record.

  S6: When the session is not established (distribution is not started), the transmission / reception unit 51 of the management system 50 transmits a message to that effect to the guest terminal 10abab. The display control unit 17 of the guest terminal 10abab displays that the distribution has not started.

  S7: When the session has already been established, the determination unit 61 of the management system 50 determines whether or not the master has entered the conference. Specifically, the related communication ID associated with the guest communication ID is acquired from the guest room entry management table. Next, the session management DB 5005 is searched using the session ID acquired in step S5 as a search key, and the communication ID of the master terminal 10ab corresponding to the related communication ID is included in the destination terminal field of the searched record. It is determined whether or not. Thereby, it is possible to check whether the communication ID of the master has started a session.

  S8: When the terminal 10ab corresponding to the master communication ID is included in the session management DB, the notification unit 62 of the management system 50 starts viewing the video by the guest terminal 10abab with the terminal 10ab of the related communication ID as the destination. Notify you. Since no approval is required, the master guardian can save time and effort to approve every time grandparents enter the room.

  Note that the notification unit 62 of the management system 50 does not have to notify the terminal 10ab of the related communication ID that the guest terminal 10abab has started browsing the video. When a large number of guests enter the room in a short time, it is possible to prevent the parents from feeling troublesome. Even in this case, the master can obtain a list of guests entering the room from the management system 50 at an arbitrary timing. Thereafter, the process proceeds to step S13, and the management system 50 starts a session with the guest terminal abab.

  S9: When the terminal 10ab corresponding to the communication ID of the master is not included in the session management DB, the determination unit 61 of the management system 50 checks the approval field of the guest entry management table.

  S10: When the approval field is x (unapproved), the notification unit 62 of the management system 50 transmits to the mail address registered in the master communication ID that the guest terminal 10abab is about to view the video. To do. If the approval field is ◯ (approval), the process proceeds to step S13, and the management system 50 starts a session with the guest terminal 10abab.

  S11: When the rejection of approval is notified from the master terminal 10ab, the notification unit 62 of the management system 50 notifies the guest terminal 10abab that the room cannot be entered.

  S12: If approved, the conference management unit 59 of the management system 50 sets the approval field of the guest room entry management table to ○.

  S13: In the management system 50, the session management unit starts a session with the guest terminal 10abab. That is, the session ID retrieved in step S7 is retrieved from the session management DB 5005, and the communication ID of the guest terminal 10abab included in the room entry request is added to the destination terminal field of the retrieved record.

  S14: The transmission / reception unit 51 of the management system 50 transmits the session ID and the relay device connection information (IP address, authentication information, port number, etc. of the relay device 30) to the guest terminal 10abab that transmitted the entry request. With the above processing, the processing for connecting the guest terminal 10 to the relay device 30 is completed. Next, the guest terminal 10abab transmits relay request information to the management system 50, and starts a process of requesting relay of call data. Thereby, the terminal 10abab of the guest who has transmitted the entry request by accepting the selection of the meeting room name included in the meeting room list from the user starts communication using the meeting room.

  Next, the process of FIG. 17 will be described. FIG. 17 is an example of a flowchart illustrating a procedure performed by the management system 50 when a guest enters the conference room. In FIG. 17, processing that has not been described in FIG. 16 will be mainly described. The process of FIG. 17 starts when the guest presses the room entry button 1301 and the guest terminal 10abab receives it (S1).

  Steps S2 and S3 have been described with reference to FIG. Next, in step S3-2, the conference management unit 59 of the management system 50 determines whether or not to permit entry (S3-2). Specifically, it is determined whether or not the current date is valid. This determination method is the same as step S7 in FIG. The reason for the determination again in FIGS. 16 and 17 is that the date may change between the determination in FIG. 15 and the determination in FIGS.

  The next steps S4 to S10 have been described with reference to FIG. In step S10-2, it is determined whether or not the determination unit has been approved. The master approves or rejects the guest viewing the video by accessing the URL notified by the e-mail in step S10 and pressing an “approval” “reject” button. The processing in steps S11 to S14 has been described with reference to FIG.

  Since the master may not be aware of the e-mail, if “approval” and “rejection” are not transmitted to the management system 50 even after a predetermined time has passed after sending the approval request, the determination unit of the management system 50 rejects It is assumed that

<Screen example>
A screen displayed on the guest terminal 10abab will be described with reference to FIG. FIG. 18 shows an example of the transition of the screen displayed on the display 120 by the guest terminal 10abab. FIG. 18A is the same screen as FIG. 9A, and is displayed when the guest performs an operation for requesting video distribution (starts the distribution application).

  Assume that the master does not enter the conference room when the guest presses the entry button 1301. Therefore, as described with reference to FIGS. 16 and 17, the management system 50 requests approval processing from the master. In order to make the guest know that the guest terminal 10abab is waiting for the master's approval, the display control unit 17 of the guest terminal 10abab displays a message 521 as shown in FIG. This message 521 displays “Requesting approval for viewing from Mr. XXX”. XX is the master terminal name.

  When the master approves, the management system 50 establishes a session with the guest terminal 10abab and starts video distribution. Thereby, as shown in FIG.18 (c), the terminal 10abab of a guest can display an image | video.

  FIG. 19A is a diagram illustrating an example of a screen displayed on the master terminal 10ab. When the guest terminal 10 starts browsing the video, the master terminal 10ab also enters the same conference room and browses the video. In this case, the management system 50 does not perform approval by the master, but notifies the master terminal 10ab that the guest will enter the room. That is, the management system 50 acquires the master communication ID associated with the guest communication ID from the guest entry management table, identifies the master, and transmits a message to the master terminal 10ab.

  As shown in FIG. 19A, the master terminal 10ab displays, for example, a pop-up message 531 “Grandparents have started browsing”. This “grandparent” can be read by the management system 50 from the related field of the guest terminal management table. Therefore, the master can grasp who started viewing the video.

  FIG. 19B is a diagram illustrating an example of a screen displayed on the terminal 10aa of the nursery school. A nursery school administrator may want to check who is currently viewing the video. When a nursery school administrator or the like performs an operation for displaying a list of viewers, the terminal 10aa accepts this operation. The nursery school terminal 10aa displays on the display 120 the master communication ID 541, the guest communication ID 541, the information 542 of the related fields in the guest entry management table, and the like.

  Specifically, the terminal 10aa transmits a browser list request to the management system 50 together with the communication ID. The management system 50 searches for the request source terminal in the session management table by the communication ID and identifies the communication ID of the destination terminal. This communication ID can be a master ID or a guest ID. The communication ID registered in the guest room entry management table is a guest, and the management system 50 acquires information on the related fields. Further, the terminal name can be acquired by searching the master communication ID in the terminal management table.

  Therefore, the screen of FIG. 19B can be displayed from these pieces of information. The terminal name may be displayed together with the communication ID 541 or instead of the communication ID. Note that the same processing can be performed by the master terminal 10ab.

  As described above, in the transmission system 1 of the present embodiment, when a grandparent or the like logs in as a guest, the notification mode that the guest logs in is changed depending on the login status of the guardian. Can reduce the burden on the master. In other words, it is possible to automatically select whether approval is required or notification only, and a master procedure necessary for the guest to view the video can be made appropriate.
